Ordered Statistics Decoding of Linear Block Codes Over Intersymbol Interference Channels
Fabian Lim, A. Kavcic, Marc Fossorier · IEEE Transactions on Magnetics · 2008
In this paper, we utilize ordered statistics decoding (OSD) techniques for intersymbol interference (ISI) channels. To achieve good efficiency and storage complexity, a combination of a modified generalized Viterbi algorithm (GVA) and Battail's algorithm is proposed to implement OSD for ISI channels. Simulation results showed significant performance improvement for the [128,64,22] eBCH code, and the [255,239,17] Reed-Solomon (RS) binary image, on the (1+D)2perpendicular recording channel.
